STAMPAFFIXING MACHINE.

Application filed J' une 30, 1914. Serial No. 848,290.

To all whom t may concern.'

Be it known that I, WILLIAM F. SCHWEI- GER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Stamp- Aflixing Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specication, and to the reference-numerals marked thereon.

My invention relates to stamp aiiiXing machines, and it has for its object to improve the construction of the parts so as to lessen the cost of manufacture, and to aiiord a combination by which the operation of the mechanism is improved. More particularly, the invention contemplates a novel construction for the strip engaging and feeding lingers, both as to the formation of the inger as well as to the method of mounting. To these and other ends the invention consists of certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being` pointed out in the claims at the end of the specification.

In the drawings:

Figure l is a vertical sectional view of a portion of a stamp ailixer, showing-the application of my improvement;

Fig. 2 is a sectional view on the line 2 2 of Fig. l;

Fig. 3 is a front elevation of the parts shown in Fig. 2;

Fig. 4 is a side elevation of the same;

Fig. 5 is a vertical sectional View of the structure shown in Fig. 4;

Fig. 6 is an edge elevation vof one oflthe fingers, and

Fig. 7 is an end elevation of the same.

Similar reference numerals in the several figures indicate the same parts.

In illustrating a preferred embodiment of the invention, I have disclosed a well known form of stamp aifiXing machine comprising a casing l and a strip supporting roll 2 on which is arranged the stamp strip 3. For the understanding of the present structure, it will be .unnecessary to describe fully the Specification of Letters Patent.

operation of the machine further than to state that there is a plunger 4 that is adapted to be depressed, and carries means for engaging and feeding the stamp strip as well as devices for severing each-stamp from the strip and impressing it upon the surface to which it is to be attached, and the present application does not contemplate any novel construction of the plunger or of the stamp severing means, but is directly associated with the devices which are mounted on the plunger for engaging and feeding the stamp strip.

' In the present construction the plunger 4 is shown provided with suitable bracket arms 5 to which is attached a support 6 embracing side walls 7 arranged in spaced relation to each other and an overhanging top S. Mounted upon the support 6 is a series of fingers or feelers which engage the perforations between the stamps of the strip as the plunger 4 is reciprocated. The fingers are pivoted upon a bearing or spindle 9 which is secured and extends between the walls 7, and

each finger comprises a body portion l0 which is hollow for a portion of its length, and preferably of substantially U-shaped formation in cross section, while 1l designates the end or strip engaging portion of the iinger which is of reduced thickness as shown in Fig. 6. The finger may be formed from a sheet metal blank by bending the metal upon itself, the walls being pressed into contact at the end portion ll, while the walls of the body portion remain in spaced relation to each other, as shown in Fig. 6. Each finger is actuated by a spring l2 which is secured at its inner end to a post 13 attached to the walls 7 of the support 6L The spring 12 extends over thebearing 9 and has its free end bent to form a right angle portion which engages the hollow part of? the finger and is freely movable between the walls l0 of the body portion. It will be seen that the normal tendency of the spring is to move the free end of the linger upwardly, as shown in Fig. 5, so that it engages the stamp strip and is held in engagement therewith under the proper resilient action to permit the fingers to yield in moving upwardly over the strip. It is necessary, however, to limit the movement of the fingers on the support and to this end I provide each finger with a recess or opening adapted to be engaged by a suitable projecting device stationarily mounted on the support. This is preferably accomplished by openings 15 formed in the side walls of the fingers, and receiving a stop bar or rod 16 which extends through the openings in the several fingers and is attaohed to the walls 7 of the support. The diameter of the rod 16 isy less than that of the openings 15 so that a slight freedom of movement of the fingers is permitted, against the action of the springs. lith this construction, it becomes unnecessary to employ spacing devices between the adjacent lingers, as the body portion of each finger is of greater thickness than the strip engaging portion so that the extremities of the fingers are properly spaced to engage the perforations of the strip when the fingers are mounted on the bearing in juxtaposition to each other.

The construction described affords an extremely simple and unique arrangement which does not involve any expensive operations in the manufacture and which pel'- forms the required work efficiently and accurately in the combination for which it is desired.

I claim as my invention:

1. In combination with a support, a finger pivotally mounted thereon and comprising a body portion that is hollow for a portion of its length, and a spring having one end connected to the support and its opposite end freely movable in said hollow portion of the finger.
